Zinc Plated Steel

Zinc plated steel is very common in the fastener industry. Zinc adds a layer of corrosion resistance to plain alloy steel. Clear zinc has a light, shiny color and blue zinc has a bright blue hue. Zinc plated steel is not suitable for extreme environment use, as it is not as resistant to corrosion as hot dipped galvanized.

A Phillips Flat Head Machine Screw is driven with a Phillips, or cross bit. Phillips Flat Head Screws are also known as machine screws, Phillips screw or machine screw bolt.
